\

The parabola equation is $\"\"$ .

\

Write the equation in a translated form of a parabola $\"\"$ .

\

Where $\"\"$ is the vertex of the parabola,

\

$\"\"$ is the directed distance from vertex to focus,

\

Focus is $\"\"$ , and equation of the directrix is $\"\"$ .

\

$\"\"$

\

The parabola equation is $\"\"$ .

\

$\"\"$

\

To change the expression into a perfect square trinomial add $\"\"$

\

to each side of the equation.

\

The $\"\"$ coefficient is $\"\"$ , $\"\"$

\

Add $\"\"$ to each side.

\

$\"\"$

\

Compare the above equation with translated form of a parabola $\"\"$ ,

\

Vertex is $\"\"$ .

\

$\"\"$ .

\

Focus is $\"\"$ : $\"\"$ .

\

Equation of the directrix:

\

$\"\"$

\

Vertex is $\"\"$ , focus is $\"\"$ , and directrix is $\"\"$ .

\

$\"\"$

\

The parabola is $\"\"$ . \

\

Vertex is $\"\"$ , focus is $\"\"$ , and directrix is $\"\"$ .

\

Make the table of values to find ordered pairs that satisfy the equation.

\

Choose values for $\"\"$ and find the corresponding values for $\"\"$ .

\

1. Draw a coordinate plane.

\

2. Plot the vertex and focus of the parabola.

\

3. Plot the ordered pairs found in the table.

\

4. Connect those plotted points with a smooth curve.
